Force Play?

[gxc]

Greymule,
Yes, technically BR is not forced to 1B by a following runner, but BR never has a base he can return to, so he is "forced" to 1B.

In the case where BR obtains 1B but retreats back to home, the force is back on, just as it would be at 2B or 3B if a runner retreats back from the base that he was forced to. In all three cases, the runners have no where else to go except to the next base.
